Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522998, here are decompositions:

  • 11 + 31522987 = 31522998
  • 19 + 31522979 = 31522998
  • 37 + 31522961 = 31522998
  • 47 + 31522951 = 31522998
  • 61 + 31522937 = 31522998
  • 97 + 31522901 = 31522998
  • 109 + 31522889 = 31522998
  • 151 + 31522847 = 31522998

Showing the first eight; more decompositions exist.
